Ghost block / Phantom Block

Since a few snapshots I'm getting quite a few "ghost blocks". I don't think it's the same issue as MC-62166 because in my case, when I mine something very fast, for example dirt with efficiency 4 or stone with efficiency 5 and a beacon with haste II, blocks do disappear but they are still there. They are just invisible until the chunk is reloaded (quit/save and reload makes the already broken block reappear; also placing a block at the same spot). Also I can't walk through them, it creates a weird stuck animation.

As far as I understand it, even in single player I'm playing on a local server? Could there be a discrepancy between the client and the server? I think it started happening after a developer (I can't recall who specifically 😞) tweeted he fixed a few cases of block lag (could be coincidence though).

MC-63551, which sounds like the thing I'm experiencing, was closed as a duplicate of MC-62166 which itself is closed as can't reproduce. I have been able to reproduce it A LOT on my snapshot world. If this is infact a duplicate, please reopen MC-62166 as it is clearly not fixed.

It might be related to MC-55106 but like I said, it happens with dirt and stone as well!

If needed I can try to catch it on video.

Yes, please attach a video.

It was quite easy to reproduce. I made a new world, a diamond shovel with eff 5 and unbreaking 3 and digged away resulting in multiple ghost blocks. The first ghost block I unfortunately replace with dirt, but you can notice the missing sound when placing it. The second ghost block is replaced with iron and turns back into dirt. With the third block I show that it appears as soon as I reload the world.

edit2: What might be of further interest: I have the frame rate set to unlimited and I get around 200 FPS.

I hope this helps!

edit: please notice the anonymous chicken, which just HAD to be in the shot 😉

Duplicate of MC-858, which I will now untangle per a commenter's request there.

Just for reference, I think you meant to duplicate it with MC-5694

(also I have to improve my searching skills, as I could not find these issues beforehand)

MC-5694 was closed until a few minutes ago, I'm not going to bother relinking all the duplicate links to that one.
